What should you create?

You have a server named Server1 that runs Windows Server 2012 R2.
You connect two new hard disks to Server1.
You need to create a storage space that contains the two disks.
The solution must meet the following requirements:
Provide fault tolerance if a single disk fails.
Maximize the amount of files that can be stored in the storage space.
What should you create?

A.
a parity space

B.
a simple space

C.
a spanned volume

D.
a mirrored space

Explanation:
Fault tolerant and better space ratio.The data on volumes created on this type of virtual disk,
together with parity information that can be used to facilitate automatic reconstruction of data
in the event of a physical disk failure, is striped across all physical disks in the pool. Parity
virtual disks also provide resiliency to help protect you from data loss arising from the failure
368 Chapter 8 File services and storage of a physical disk in the pool, but they perform
better with large sequential disk writes than with random I/O.

Incorrect answers:
A) A simple space stripes data across a set of pool disks, and is not resilient to any disk
failures.
B) A spanned volume is a dynamic volume consisting of disk space on more than one
physical disk and not fault tolerant
C) Fault tolerant dependent on the amount of physical disks in the pool, but no max space
for storage purposes.
